A coin C of mass 0.050 kg is placed on a horizontal disk at a distance of 0.20 m from the center, as shown above. The disk rotates at a constant rate in the clockwise direction as seen from above. The coin does not slip, and the time it takes for the coin to make a complete revolution is 1.2 s. a. The figure below shows the disk and coin as viewed from above. Draw and label vectors on the figure below to show the instantaneous acceleration and linear velocity vectors for the coin when it is at the position shown. b. Determine the speed of the coin. c. The rate of rotation of the disk is gradually increased. The coefficient of static friction between the coin and the disk is 0.50. Determine the speed of the coin when it just begins to slip. d. If the experiment in part (c) were repeated with a second, identical coin glued to the top of the first coin, how would this affect the answer to part (c) ? Explain your reasoning.

one end of a cord is fixed and a small 0.5 kg object is attached to the other end , where it swings i a section of a vertical circle of radius 2 mas shown i figure attached. when teta= 20 degrees, the speed of the object is 8m/s. at this instant, find the tension in the string, find  the tangential ad radial components of acceleration, and find the total acceleration. is your answer changed if the object is swinging down toward its lowest point instead of swinging up? explain the answer.
